Sitting down at the family's Atlanta home on Monday to discuss their son's death, Christina and David Roy Ferguson said they have been told by Jacksonville police detectives their son likely fell to his death from the parking deck while sleepwalking.

Christina Ferguson said she had seen her son sleepwalk before, while her son's roommates told the family they, too, witnessed Davy sleepwalking several times at their apartment in Gainesville near the UF campus.
